Typical latencies: sub-second to few seconds for local SCADA points; 4–60 seconds for telemetry to dispatch centers depending on link and protocol.
Accuracy depends on metering class (CT/VT accuracy), calibration, and timestamping; synchronized time (NTP/GPS) is critical for settlement-quality data.
4. Challenges in Real-Time Generation Management
2. Real-Time Data Architecture
Frequency control: If grid frequency drops below 49.9 Hz, SLDC instructs WBPDCL to increase generation in real time.
Merit order dispatch: Cheaper stations (Sagardighi newer units) run at higher load factors.
